Do you see a $ WinREAgent folder on your C drive? And maybe asking me what it is for. Well, such folders with the sign “Dollar” $ indicate that the folder is hidden and they are used to create during the installation phase and continue for a limited period of time.
What is the $ WinREAgent folder in Windows 10
The $ WinREAgent folder is usually created during an upgrade or update and is used in case a restore is necessary.
It is created by Windows recovery environment which works as a solution when the system does not start. WinRE can repair common problems that prevent the Windows operating system from starting. When it is finished, most of its content is deleted.
